bluetooth questions

[james tech]

heelo every one ,

i want to use bluetooth to connect my nrf51822 to my smartphone can anyone help me because i don't have any idea there is any example ready to use plz

Hi Fares Elec!

You can use one of the examples in one of our SDK's.
The latest supported SDK for the nRF51822 is SDK v12.3.0.
There are precompiles hex-files you can flash to your board that will allow you to connect your smartphone.
Remember that you will not be able to connect to most BLE devices directly from your phone's bluetooth settings. You will most likely need a mobile app to connect to your device.

For example;
You can flash the ble_app_uart example to your device, and use the nRF Toolbox app (available on Android, iOS and Windows phone) to connect to the device.
You can read more on the infocenter-page of the UART-example about how to test it with your device.

Best regards,
Joakim.

hi Joakim it was very helpful but i'm wondering about something when i tried to use sdk 12.0 i wasn't able to connect to the ble from my android phone using the setings but whene i used sdk 9.0 i wase be able how can you explaine that

Hi!
What kind of phone are you using?
Are you using the same example in both SDK 12 and 9?
Some services are natively supported on some phones. For example, HID, HRS, and ANCS is supported by iOS and you will be able to search and connect through the bluetooth settings on your phone.
Best regards.

Not sure if I understand what you mean by "strong text".
